Devices stop syncing

Hey Corey! This is probably the single biggest we have with JamfSchool. Have never been able to figure it out. Sometimes restarting the device helps, however most of the times the device has to be returned to me. I try to figure it out. Sometimes I even have to erase the device to start over.

Yes i have had to erase a few devices as well. And i pulled a list at our HS and we have around 50 devices that are at 2 weeks. But we are seeing it a lot recently due to exams and teachers trying to use Jamf Teacher. And last time i went in to battle with Jamf Support about this and jamf teacher/student not Appling lessons i got told it was how apple does things now. And then Apple said no its how the developed it. So I'm at a stand still of what do we do. 

Have you tried removing the wifi from the issue (take the device to a entirely different wifi area and see if the connection goes through).  I had one district that I worked with that had similar issues but if you took the device and hooked up to Mcdonalds wifi or my xfinity wifi, the device responded instantly.  Turned out their wifi needed some tweaking.

In the hail mary category of things from a weird experience I had with Jamf Pro last year.

We were pushing out a wallpaper configuration profile at only one of our schools and it turned out to be the culprit causing a large number of their devices to stop responding in this manner. It makes me wonder if there is a certain configuration profile that may be causing it because some underlying bug.

I feel like this also happened with a webclip linked to a PDF of book at one time as well.

In your environment are there certain devices it happens to and not others - students vs. teachers? That may help narrow your search for a particular configuration profile specific to devices that develop the issue.

​@Corey-Ribble -- I’m going to run this by the team and see if anyone has any insight. It would be helpful to know if it’s the same devices -- if you have any s/n you can pass along, that’d be helpful too! 

Hello Tracey, i have a few Serial Number examples in the support ticket i opened a day or so ago. (#79200440). I even went through the documentation for what ports and links need to be unblocked to rule out network as well. Jumping through a bunch of hoops to troubleshoot we can get the devices talking again, but i have 3k ipads and if had to do restarts, airplane mode and other steps each time then my users will just stop using the devices.

I helped track down something similar in a Jamf Pro environment.  Finally found the culprit by looking at what all the configuration profiles do, and the local device logs.

Basically, one of the cofiguration profiles was bad and seemed to prevent things from processing, like it was still trying to apply the bad configuration profile but not generating an error and continuing.  I un-scoped this one configuration profile from the device and the device immediately started getting the policies and eveything seemed good.

​@Corey-Ribble -- I ran this by the team and you’re in good hands with the bread and butter folks assisting you! 

So after a lot of hunting with the JAMF Support team we finally found a log file that explains whats happening. And it seems to be a bug in the iPADOS not JAMF for this issue. And they have reported it to Apple so we will see what happens.
